apollo-angular - hangs on `pending` status with network call

I intergrated angular18 with apollo-angular. when i try to fetch the call from gihub.com the network call hangs on pending state.

here is my provider for apollo-angular:

import { ApplicationConfig, inject } from "@angular/core";
import { ApolloClientOptions, ApolloLink, InMemoryCache } from "@apollo/client/core";
import { setContext } from "@apollo/client/link/context";
import { Apollo, APOLLO_OPTIONS } from "apollo-angular";
import { HttpLink } from "apollo-angular/http";

export const githubData = {
  token: "ghp_M4T0mxxxxxxxUqnI4BHWyD6dGmQLk3Fovcb",
};

const uri = "https://api.github.com/graphql";

const header = setContext((operation, context) => ({
  headers: {
    Accept: "charset=utf-8",
  },
}));

const auth = setContext((operation, context) => {
  const token = localStorage.getItem("token");

  if (token === null) {
    return {};
  } else {
    return {
      headers: {
        Authorization: "bearer " + githubData["token"],
      },
    };
  }
});

export function apolloOptionsFactory(): ApolloClientOptions<any> {
  const httpLink = inject(HttpLink);
  const link = ApolloLink.from([header, auth, httpLink.create({ uri })]);
  return {
    link: link,
    cache: new InMemoryCache(),
  };
}

export const graphqlProvider: ApplicationConfig["providers"] = [
  Apollo,
  {
    provide: APOLLO_OPTIONS,
    useFactory: apolloOptionsFactory,
  },
];

My service :

import { Injectable } from "@angular/core";
import { gql, Query } from "apollo-angular";

@Injectable({
  providedIn: "root",
})
export class GitServiceService extends Query<Response> {
  document = gql`
    query {
      user(login: "3gwebtrain") {
        issues(first: 10) {
          nodes {
            title
            body
            closedAt
          }
        }
      }
    }
  `;
}

my component:

import { Component, inject, OnInit } from "@angular/core";
import { RouterOutlet } from "@angular/router";

import { GitServiceService } from "./services/git-service.service";
@Component({
  selector: "app-root",
  standalone: true,
  imports: [RouterOutlet],
  templateUrl: "./app.component.html",
  styleUrl: "./app.component.scss",
})
export class AppComponent implements OnInit {
  gitService = inject(GitServiceService);
  ngOnInit(): void {
    console.log("Hellow there");
    this.gitService.watch().valueChanges.subscribe((data) => console.log("data", data));
  }
}

when component loads, getting network status as pending and hanged.

This if condition will always return false, so your request is made without the auth token.

const auth = setContext((operation, context) => {
  const token = localStorage.getItem("token");

  if (token === null) { // <- token is never set so it will always go to if condition
    return {};
  } else {
    return {
      headers: {
        Authorization: "bearer " + githubData["token"],
      },
    };
  }
});

Also the auth token seems to be of different length, can you set the auth token Generate Auth token
